The United States has accused Iran of repeated "violations and evasions" of its UN nuclear safeguards agreement and demanded Tehran unconditionally accept tighter UN inspections of its atomic facilities.
"If Iran's intentions are peaceful, why did it engage in a long-term pattern of safeguards violations and evasions regarding a number of its nuclear...activities," US ambassador to the United Nations in Vienna, Mr Kenneth Brill, told the UN agency's governing board.
